水-能纽带关系下中国省际煤炭水足迹空间转移特征分析
Spatial Transfer Characteristics of Inter-provincial Coal Water Footprint in China under Water-energy Nexus
摘要
Abstract
The energy water footprint is often used to represent the real consumption of regional water resources in the pro-duction process of energy.This paper adopts a bottom-up approach to analyze the temporal and spatial changes in the water footprint of coal in each province or municipality or district of China from 2015 to 2019.On this basis,the spatial transfer network characteristics of inter-provincial coal water footprints in China are explored.The results are as follows.During the study period,the water footprint of China's coal showed a fluctuating upward trend,with the blue water footprint and gray water footprint accounting for 21.56%and 78.44%of the total water footprint on average,respectively.Spatially,the re-gions with high coal water footprint are mainly distributed in Shaanxi,Shanxi and Inner Mongolia in the Yellow River Ba-sin,and their spatial distribution pattern is relatively consistent with the spatial distribution of total coal production.In terms of spatial transfer of coal water footprint,Shanxi,Shaanxi and Inner Mongolia are the largest exporters of coal water footprint.Among them,the coal water footprint of Shanxi mainly flows to Hebei and Shandong,the coal water footprint of Inner Mongolia mainly flows to northeast China,Shandong and Jiangsu,and the coal water footprint of Shaanxi province flows to the surrounding provinces.During the study period,Hebei,Shandong and the southeastern coastal region were the major coal water footprint inputs,while Shanxi,Shaanxi and Inner Mongolia were the regions with large net outflow of coal water footprint.关键词
